AJA KONA LHe Plus Installation And Operation Manual page 42

This in effect makes the KONA card a converter. No applications other than the
AJA Control Panel need be open to convert audio and video from one format to
another. For example, if you have KONA 3G or LHi and need to dub an SD source
tape needs to be HD, the signal can be routed from the SD VTR to the KONA card
configured for up-conversion in the AJA Control Panel and then passed through
to the HD VTR for recording. (Note: LHe Plus performs down-conversion only.)
Test Pattern
This selection directs the KONA card to output a choice of preset pattern when no
other application is using the KONA card. You can choose from:
Black, Color bars (75% or 100%), Ramp, Multiburst, Line Sweep, Multi Pattern, or
Flat Field.
In addition to the preset test pattern choices, a "Load File..." selection at the
bottom of the menu allows you to load any standard RGB graphics file (.tif,.psd,
etc.) into the frame buffer for display.
While in Test Pattern mode, you can select RGB or YUV output via a pulldown
menu.
NOTE: The graphic file will not be scaled to fit. If it's smaller than the current frame
Hold Last App
This selection directs KONA to hold and output the last frame of video from
the last application to control KONA. This can be helpful when operating in
an environment where you're switching back and forth between multiple
application windows.
Playback Timing
Use these controls to set Genlock and Timing adjustment.
Genlock
Selects how KONA will synchronize program video:
Freerun: In this mode, KONA generates sync without an external reference source
Ref In: Directs KONA to use the Ref Video source for sync (usually an analog black
burst video signal)
Video In: Directs KONA to use whichever video input source has been selected in
the Inputs Screen for sync
Timing (Horiz and Vert):
These two pull-downs allow output timing adjustment with reference to the Ref
Video source selected:
• Horizontal selects a number of pixels (clocks) to offset
• Vertical specifies a number of lines to offset

buffer format, KONA will center it in the frame. If it's larger than the current frame
buffer format, it will be cropped on the right and bottom. Also some graphics
formats and bit depths may not be supported. Once a graphic file is loaded into
the frame buffer it will be retained until it is overwritten by another graphic or test
pattern, or when power is turned off. Graphic file names are only "remembered"
in the menu until the AJA Control Panel application closed.
